The photocatalytic oxidation of Rhodamine B (RhB) was studied using immobilized TiO2 and fluidized bed reactor. Immobilized TiO2 onto GF/C was employed as the photocatalyst and a 30 W germicidal lamp was used as the light source and the reactor volume was 4.8 L. The effects of parameters such as the amounts of photocatalyst, initial concentration, initial pH, air flow rate and anion additives (NO3-, SO42-, Cl-, CO32-) competing for reaction. The results showed that the optimum dosage of the immobilized TiO2 was 40.0 g/L. Initial removal rate of immobilized TiO2 was expressed Langmuir - Hinshelwood equation.
